OVERHEAD ZERO VOLT IONIZER
Installation, Operation, and Adjustment Instructions
The Overhead Zero Volt Ionizer combines the effectiveness of steady-state DC
ionization with ease of adjustability, communication capability, and the flexibility of a micro-
controller based design to produce a versatile and stable ionization system. Three fans
produce extended ionization coverage, and are ideal for areas where bench space is limited.
